• TypeScript: only add trailing commas in tuples for --trailing-comma=all (#6199 by @duailibe)

  In Prettier 1.18 we added trailing commas in tuples when --trailing-comma=all, but it was also adding for --trailing-comma=es5.

• TypeScript: Add trailing comma in tsx, only for arrow function ([#6190] by [@sosukesuzuki])

  Prettier inserts a trailing comma to single type parameter for arrow functions in tsx, since v 1.18. But, this feature inserts a trailing comma to type parameter for besides arrow functions too (e.g, function , interface). This change fix it.

  // Input
  interface Interface1<T> {
    one: "one";
  }
  function function1<T>() {
    return "one";
  }
  
  // Output (Prettier 1.18.0)
  interface Interface1<T,> {
    one: "one";
  }
  function function1<T,>() {
    return "one";
  }

  }
  

• Config: Match dotfiles in config overrides ([#6194] by [@duailibe])

  When using overrides in the config file, Prettier was not matching dotfiles (files that start with .). This was fixed in 1.18.1

    if (true) {
      call("this line is 79 chars", "long", "it should", "stay as single line");
    }

  // Output (Prettier 1.17.0 run with --range-start 30 --range-end 110)

        "long",
        "it should",

  }
  

• JavaScript: Fix closure compiler typecasts ([#5947] by [@jridgewell])

  If a closing parenthesis follows after a typecast in an inner expression, the typecast would wrap everything to the that following parenthesis.

  <!-- prettier-ignore -->

  // Input
  test(/** @type {!Array} */(arrOrString).length);
  test(/** @type {!Array} */((arrOrString)).length + 1);
  
  // Output (Prettier 1.17.0)
  test(/** @type {!Array} */ (arrOrString.length));
  test(/** @type {!Array} */ (arrOrString.length + 1));
  
  // Output (Prettier 1.17.1)
  test(/** @type {!Array} */ (arrOrString).length);
  test(/** @type {!Array} */ (arrOrString).length + 1);
  

• JavaScript: respect parenthesis around optional chaining before await ([#6087] by [@evilebottnawi])

  <!-- prettier-ignore -->

    var x = (await foo.bar.blah)?.hi;
  }
  
  // Output (Prettier 1.17.0)
  async function myFunction() {
    var x = await foo.bar.blah?.hi;
  }
  
  // Output (Prettier 1.17.1)
  async function myFunction() {
    var x = (await foo.bar.blah)?.hi;
  }

• JavaScript: Improved multiline closure compiler typecast comment detection ([#6070] by [@yangsu])

  Previously, multiline closure compiler typecast comments with lines that start with * weren't flagged correctly and the subsequent parenthesis were stripped. Prettier 1.17.1 fixes this issue.

  <!-- prettier-ignore -->

  // Input
  const style =/**
   * @type {{
   *   width: number,
   * }}
  */({
    width,
  });
  
  // Output (Prettier 1.17.0)
  const style =/**
   * @type {{
   *   width: number,
   * }}
  */ {
    width,
  };
  
  // Output (Prettier 1.17.1)
  const style =/**
   * @type {{
   *   width: number,
   * }}
  */({
    width,
  });

• API: Fix prettier.getSupportInfo() reporting babel parser for older versions of Prettier. ([#5826] by [@azz])

  In version 1.16.0 of Prettier, the babylon parser was renamed to babel. Unfortunately this lead to a minor breaking change: prettier.getSupportInfo('1.15.0') would report that it supported babel, not babylon, which breaks text-editor integrations. This has now been fixed.
